This patent application claims the benefit of U.S. Provisional Patent Application Ser. No. 62/785,496 filed on Dec. 27, 2018 and entitled “Container Having Multiple Separate Internal Reservoirs,” the disclosure of which is hereby incorporated by reference herein in its entirety and made part of the present U.S. utility patent application for all purposes.

BACKGROUND OF THE INVENTION

The present invention relates generally to packages and containers for use with commercial products such as adhesives, paint, and the like and more specifically to a container that includes multiple internal reservoirs that are separated from one another in a manner that allows the container to store at least two fluid or viscous materials that differ from one another in their chemical and physical properties.

Most containers used for commercial products such as adhesives or paint include only a single internal reservoir for holding the contents of a container. When a multi-part adhesive system or other type of system requiring the sequential mixing of multiple materials having different chemical and physical properties (e.g., a resin and its curing agent) are sold commercially, a separate container is typically required for each material to prevent premature or unwanted mixing of the materials. The necessity of multiple, separate containers for such products add expense and complexity to the packaging process and is often inconvenient for the users of such products with regard to transporting and using the products. While certain containers for storing multiple different materials do exist, these containers are often expensive to manufacture and lack the aesthetic qualities that consumers expect with regard to containers traditionally used for do-it-yourself products (e.g., adhesives) and products for use with toys and stationery (e.g., paints, liquid glitter, etc.). Thus, there is an ongoing industrial and commercial need for a simplistic container that includes multiple, separate, internal reservoirs for storing at least two fluid or viscous materials that differ from one another in their chemical and physical properties and that meets the aesthetic and practical expectations of the typical consumer.
